In the 10 years of the UW weather station the first frost day has ranged between October 2nd and October 28th, with the average coming in around the 11th.

But no matter if it does actually go below zero at the station, depending on your particular location there is a good chance that you will get frost and you should make appropriate arrangements for your delicate plants.

In the 10 year history of the UW weather station, the temperature in September has been the most above the average of any month and this year is no different. In total, 8 of the last 11 Septembers have been above average and the other 3 have been average with none below average (looking back the Environment Canada archive, 1993 was the last time we had a cold September). This year it was 1.6 degrees warmer than the standard average period of 1971-2000.

We were on a torrid pace during the first half of the month with 107.6 mm of precipitation by the 15th, however since then we have only had another 8.6 mm. This still puts us far above the average of 87.5 mm, but if we had doubled the first half total it would have been something to see.

With 862.9 mm of precipitation at the end of September, this is now the 5th wettest first 9 months of the year since record keeping began back in 1915.
